Hi all. I have an '03' reg Freelander Serengeti Td4. The car has been dealer/ competant garage serviced since new at all appropriate intervals and has now done 140,000 miles ( just to let you know its not been neglected).

From time to time when pulling away and steady throttle sometimes I am experiencing a rattle from the engine (sounds like a kid quickly dragging a stick across railings) , the engine stutters slightly and emits black smoke from exhaust. This has been happening for a while now and it is ocassional.

I replaced all the injectors when my td4 started knocking when cold....but its worth looking at the fuel pressure sensor and plug 1st.....

Had the same problem with mine and found the common rail sensor plug corroded which is apparently a common fault . What I found on another is the cable was pinched between the inlet manifiold and the head and causing a short circuit and false pressure readings. Took a longnose pliers and twisted the sensor lugs +- 5 degrees out of line and reseated the plug a lot of times after spraying it with contact cleaner and it is now good for 6 months .
Also if you have black smoke on high revs your turbo intercooler pipes might be cracked or loose.
The best way is just check it for oil seeping out / loose clamps.
